This is a good moveset:

Swords Dance: Doubles attack stat.

X-Scissor: STAB, good power, high accuracy.

Earthquake: High power, high accuracy, double damage against Pokemon using Dig, used top deal with Poison (although not a weakness, they are annoying, Earthquake can also help against Weezing with Mold Breaker), Steel (which your moves aren't very effective against), and Fire types.

Stone Edge: High power, good chance for a critical hit, used to deal with Flying types and Fire types if Earthquake runs out of PP.

Now, since you want to max out your Speed, your Attack won't be incredibly high. As such, you'll want to get in a Swords Dance. Then you can start defeating the foe and gaining more power with Moxie. X-Scissor provides STAb. Stone Edge gives type coverage. The choice is then between Bulldoze and Close Combat. Bulldoze lowers Speed, which helps cause even with maxed Speed you'll only be at 295. Close Combat has more power, but it lowers your defenses, making you more vulnerable to priority. Your EVs give you max Speed and good Attack (you'll be getting Swords Dance and Moxie, you won't need 252 Attack EVs) and also some defense EVs to protect against priority. Lum Berry protects from status, mainly paralysis.

This is the Mega Pinsir it thought up with. Its new ability, allows Normal Type Moves to change into Flying Type Moves, which explains which Return is even there. The rest is straight up standard really. Pinsir has potential to move up with those nasty stats, the typing is what's holding it back a lot though...

X-Scissor is STAB, pretty nice power. It works. While Close Combat is great coverage even though it screws over your defenses afterard. Stone Edge is more coverage, topped with Earthquake for coverage.

Moxie is great. If you take down multiple foes wth Rock Slide or Bulldoze, you get a nice Attack boost. Bulldoze is helpful in that it lowers the Speed of your foes. In Doubles/Triples, Bulldoze is worth it. X-Scissor is STAB. Brick break is dual-screen breaking coverage.

Mega Pinsir has potential, though it is cursed with the horrible dual typing of Bug and Flying, arguably the worst typing in the game. Even with this obstruction, Aerilate is a wonderful ability, not unlike Mega Gardevoir's Pixilate, although Mega Pinsir's ability is much more useful.

The EV spread on this Pokémon may seem odd, but it is to have Mega Pinsir to be able to live at least one hit, set up a Swords Dance, then attack the next turn when it's speed has actually become the speed of the Mega Evolution.

When using this Pokémon, do keep in mind that the move Return becomes flying-type when used by this Pokemon; Return is already a devastating move, but with 153 power with stab, and the ability to be super effective, no Pokemon will enjoy taking this hit, even before a Swords Dance. Also, Earthquake is an excellent coverage move, making Mega Pinsir able reek havoc amongst all Pokemon, and not be forced to be switched out by the rock types and other common weaknesses that it's horrible typing fears.

EDIT: Turns out Mega Pinsir is S rank on Smogon. Not exactly a hidden gem.

Mega Pinsir@Pinsirite
Ability: Aerialate

Sword's Dance- You want this guy to be an all out sweeper and since Pinsir is more bulky he can max out his attack.

Quick Attack- This is like Shadow Sneak on Aegislash. Priority move boosted by Aerialate STAB and Sword's Dance.

Earthquake- Bug Flying is some pretty bad typing so this is a no-brainer for coverage.

Return/X-Scissor/Rock Slide- You can vaporize them with Return or get STAB for psychic types or more coverage.

EDIT: Adamant/Jolly nature and 252 Atk/252 Spe/4 HP. I dunno what I was thinking when I made a set for this guy so I fixed the EVs.

EDIT: Usage Tips

Mega Pinsir can be a complete monster with enough support. The obvious teammate is a Defogger/Spinner. After that get something that counters Rotom Wash and Zapdos as they both resist his Flying- Ground coverage. Now just set up and sweep.

Swords dance-boosts atk, set up for quick atk to start a sweep if wanted, np but not reliable

Quick attack-STAB with Aerialate, Piority

X-Scissor-Stab, main attacking move

E-Quake-For the ghost, rock, and steel types lurking In the shadows OR close combat-takes down rock and steel types, but defenses are lowered.

This set is pretty reliable, but main counters are rotom heat. It resists E-Quake with Levitate, resists X-Sissor, and flying type quick attack. Not to mention the OP talonflame. But other than that, this set should do fine in competitive play. It's good 155 attack with the fine 105 speed should out speed almost everything.

Earthquake- takes out Fire and Rock-Type Pokemon that you're faster than, or if you survive the first hit.

X-Scissor- For taking out Psychic and Dark-Type Pokemon.

Close Combat- HIGH attack with Adament as its Nature.

Giga Impact- Mega Evolve it and its ability changes to Aerilate which boosts Normal-Type moves and changes it to Flying-Type. Use it after you raise its attack with Moxie a few times and just DESTROY IT!!!

Adamant
Pinsirite
Aerilate
252 attack 252 speed 4 hp
x-scissor(stab)
giga impact(stab after mega)
eartquake(coverage)
stone edge(coverage)
by the way (?)izz I read the rules so am I ok now?(if you want I will delete the last sentence).

Revenge Kill with Quick Attack, get the Moxie boost, THEN Mega Evolve. Now you've got 4 attacks instead of only 3 because of Sword Dances. While it's not as powerful as a SD Mega, it still hits hard enough.
